Description

  The present invention relates to a visor, a light control system for a mobile, a control method of a visor, a control program of a visor, and a mobile.

Heretofore, various ideas have been proposed for a visor (sunlight) in a vehicle which is one of mobile bodies. Patent Document 1 discloses a configuration in which an image display device is disposed on a visor and can be used for backward confirmation and the like.
Here, when the image display device is disposed on the visor, the amount of movement of the driver's line of sight is reduced compared to the case where the image display device is disposed on the instrument panel etc. Can be provided. Therefore, it is considered that it can contribute to safe driving.

  However, since the visor essentially blocks external light such as sunlight incident from the front of the vehicle to prevent a decrease in visibility due to the external light, it is not necessary to block the external light. By evacuating to the ceiling side, the view of the passenger such as the driver is secured. Therefore, when the visor is retracted to the ceiling side, the image display device disposed in the visor can not be viewed visually, and when the visor is disposed at the use position to visually recognize the image display device, it is unnecessary. There is a problem that the view of the driver (passenger) is obstructed.

[Embodiment]
[Light control film]
FIG. 1: is sectional drawing explaining the structure of the light control film provided in the visor of embodiment.
The light control film 1 is a film-like member that controls transmitted light using liquid crystal, and is configured by sandwiching the liquid crystal cell 4 for the light control film between the linear polarizers 2 and 3.

[Linear polarizing plate]
The linear polarizing plates 2 and 3 are not particularly limited as long as they include a polarizer, and may have a polarizing plate protective film on one side or both sides of the polarizer.
For example, a polarizer is made to form a complex of polyvinyl alcohol and iodine by immersing a film made of a hydrophilic polymer such as polyvinyl alcohol (PVA) in an aqueous solution containing iodine, which is a dichroic dye, and stretching it. And a polarizer comprising a polyene oriented by processing a plastic film such as polyvinyl chloride.
When a dichroic dye is used as a dichroic dye instead of iodine, an azo dye, a stilbene dye, a methine dye, a cyanine dye, a pyrazolone dye, a triphenylmethane dye as a dichroic dye Quinoline dyes, oxazine dyes, thiazine dyes, anthraquinone dyes and the like are used.

The above-mentioned polarizing plate protective film is not particularly limited as long as it can protect the above-described polarizer and has desired transparency. As a material of the polarizing plate protective film, for example, acetyl cellulose resin, cycloolefin resin, polyether sulfone resin, amorphous polyolefin, modified acrylic polymer, polystyrene, epoxy resin, acrylic resin, polycarbonate resin, polyamide Examples thereof include thermosetting resins such as acrylic resins, urethane resins, acrylic urethane resins, epoxy resins and silicone resins, and ultraviolet curable resins. Among them, it is preferable to use an acetyl cellulose resin, a cycloolefin resin, or an acrylic resin as the above-mentioned resin material. Among them, triacetyl cellulose (TAC), which is an acetyl cellulose resin, is particularly preferable.
The linear polarizers 2 and 3 are disposed in the liquid crystal cell 4 by an adhesive layer made of an acrylic transparent adhesive resin or the like in a cross nicol arrangement. In addition, although the retardation films 2A and 3A for optical compensation are each provided in the liquid crystal cell 4 side in the linear polarizing plates 2 and 3, the retardation films 2A and 3A may be abbreviate | omitted as needed. . Further, instead of the cross nicol arrangement, the arrangement may be a parallel nicol arrangement.

In addition, you may apply the E-type linear-polarizing plate formed by the coating film comprised from the dichroism organic pigment which expresses optical anisotropy in the orthogonal | vertical direction to the linear-polarizing plates 2 and 3. FIG. Thereby, the total thickness of the light control film 1 can be made thinner.
In this case, each linearly polarizing plate is a liquid crystal layer on the liquid crystal layer 8 side of the substrate 15 of the upper laminate 5U constituting the liquid crystal cell 4 described later and on the liquid crystal layer 8 side of the substrate 6 of the lower laminate 5D. It is desirable to be disposed so as to sandwich 8. As described later, it is desirable that the substrates 6 and 15 have small optical anisotropy, but the transmitted light was variously polarized in the substrate by arranging the E-type linear polarization plate as described above. Also, it is possible to use transparent resin films with high versatility, such as PET films, as the substrates 6 and 15, because the transmitted light of the liquid crystal layer can not be affected at all. .

[Liquid crystal cell]
The liquid crystal cell 4 is configured by sandwiching the liquid crystal layer 8 by the film-like lower laminate 5D and the upper laminate 5U.

[Lower stack, upper stack]
The lower laminate 5D is formed by laminating the transparent electrode 11, the alignment layer 13 and the spacer 12 on the base material 6.
The upper laminate 5U is formed by laminating the transparent electrode 16, the alignment layer 17 and the spacer 12 on the base material 15.

〔Base material〕
Although various transparent resin films can be applied to the substrates 6 and 15, a transparent resin film having a small optical anisotropy and having a transmittance of 80% or more at a visible wavelength (380 to 800 nm) It is desirable to apply
Examples of the material of the transparent resin film include acetyl cellulose-based resins such as triacetyl cellulose (TAC), polyester-based resins such as polyethylene terephthalate (PET) and polyethylene naphthalate (PEN), polyethylene (PE), polypropylene (PP) Polyolefin resins such as polystyrene, polymethylpentene and EVA, vinyl resins such as polyvinyl chloride and polyvinylidene chloride, acrylic resins, polyurethane resins, polysulfone (PEF), polyether sulfone (PES), polycarbonate Mention may be made of resins such as PC), polysulfone, polyether (PE), polyether ketone (PEK), (meth) acronitrile, cycloolefin polymer (COP), cycloolefin copolymer and the like.
In particular, resins such as polycarbonate (PC), cycloolefin polymer (COP) and polyethylene terephthalate (PET) are preferable.
In the present embodiment, a polycarbonate film with a thickness of 100 μm is applied to the substrates 6 and 15, but transparent resin films with various thicknesses can be applied.

[Transparent electrode]
The transparent electrodes 11 and 16 are comprised from the transparent conductive film laminated | stacked on the said transparent resin film and a transparent resin film.
As the transparent conductive film, various transparent electrode materials applied to this kind of transparent resin film can be applied, and a transparent metal thin film having an oxide-based total light transmittance of 50% or more can be mentioned. . For example, tin oxide type, indium oxide type and zinc oxide type can be mentioned.

Examples of tin oxide (SnO2) include nesa (tin oxide SnO2), ATO (Antimony Tin Oxide: antimony-doped tin oxide), and fluorine-doped tin oxide.
Examples of indium oxide (In2O3) -based materials include indium oxide, ITO (Indium Tin Oxide: Indium Tin Oxide), and IZO (Indium Zinc Oxide).
Examples of zinc oxide (ZnO) -based include zinc oxide, AZO (aluminum-doped zinc oxide), and gallium-doped zinc oxide.
In the present embodiment, a transparent conductive film is formed of ITO (Indium Tin Oxide).
The specific configuration of the transparent electrodes 11 and 16 of the present embodiment will be described in detail later.

〔Spacer〕
The spacer 12 is provided to define the thickness of the liquid crystal layer 8, and various resin materials can be widely applied. Here, the spacer 12 mainly includes two types of spherical spacers (hereinafter referred to as “bead spacers”) and columnar spacers (hereinafter referred to as “photo spacers”).
Here, it is conceivable that the light control film 1 forms a photo spacer using a photolithography method in which a photosensitive resin is applied, exposed, and developed after forming an alignment layer on a base material. In this case, it is not preferable because the alignment layer is damaged by the exposure or development process to cause an alignment failure. Also, it is conceivable to apply an alignment layer after preparing the photospacer first on the substrate, but in this case, the alignment layer around the photospacer can not be provided with sufficient alignment control force. It is not preferable because it causes an orientation defect. Therefore, the light control film manufactured by the photo spacer may not be able to control the desired transmittance with high accuracy due to poor alignment.
On the other hand, the bead spacer is dispersed on the alignment layer after forming the alignment layer, and since the contact area with the alignment layer is narrow, the alignment layer as described above may be damaged or defective in alignment. Problems can be reduced.
Therefore, by applying a bead spacer as the spacer 12, it is possible to change the transmittance of the manufactured light control film 1 more precisely and finely as compared with the case of using a photo spacer.
Here, since the light control film 1 of the present embodiment is disposed in the vehicle 20, it is necessary to control the transmittance with high accuracy as needed. Therefore, in the present embodiment, a bead spacer is applied to the spacer 12.

Here, the bead spacer used for the spacer 12 can apply the well-known bead used for a liquid crystal display device, a color filter, etc. Specifically, inorganic components such as glass, silica, metal oxides (MgO, Al2O3), and organic components such as acrylic resins, epoxy resins, epoxy resins, phenol resins, melamine resins, unsaturated polyester resins, divinylbenzene Seed polymerization using core particles obtained by suspension polymerization, emulsion polymerization or emulsion polymerization of materials such as polymers, divinylbenzene-acrylic ester copolymers, diacrylic phthalate copolymers, allyl isocyanurate copolymers, etc. It is possible to use spherical, cylindrical, cylindrical or other granular bodies obtained by polymerization methods such as, porous bodies, hollow bodies and the like.
The surface of the bead spacer may be subjected to surface treatment from the viewpoint of improving the dispersibility and adhesion of the bead spacer 12 on the alignment layer. The surface coating material is not particularly limited as long as fixation to the bead surface and outflow of the chemical substance into the liquid crystal material do not matter, but examples thereof include polyethylene, ethylene / vinyl acetate copolymer A combination, ethylene / acrylic ester copolymer, polymethyl (meth) acrylate polymer, SBS type styrene / butadiene block copolymer, epoxy resin, phenol resin, melamine resin, etc. can be used.
In the above description, the spacer 12 is provided on both the upper laminate 5U and the lower laminate 5D. However, the present invention is not limited to this, and the upper laminate 5U and the lower laminate are described. It may be provided in any one of 5D.

[Alignment layer]
The alignment layers 13 and 17 are formed of a photo alignment layer. As the photo alignment material applicable to the photo alignment layer, various materials to which the photo alignment method can be applied can be widely applied. For example, photo decomposition type, photo dimerization type, photo isomerization type, etc. may be mentioned. it can.
In the present embodiment, a light dimerization type material is used. Examples of the photo-dimerization type material include cinnamate, coumarin, benzylidene phthalimidine, benzylidene acetophenone, diphenyl acetylene, stilbazole, uracil, quinolinone, maleimide, or a polymer having a cinnamylidene acetic acid derivative. Among them, a polymer having one or both of cinnamate and coumarin is preferably used in that it has a good alignment control force. As specific examples of such photo-dimerization type materials, for example, compounds described in JP-A-9-118717, JP-A-10-506420, JP-A-2003-505561 and WO2010 / 150748 are disclosed. Can be mentioned.
In addition, it may replace with a photo alignment layer, an alignment layer may be produced by a rubbing process, and a fine line-shaped uneven | corrugated shape may be formed and processed to produce an alignment layer.

[Liquid crystal layer]
The liquid crystal layer 8 can be widely applied to various liquid crystal materials applicable to the light control film 1 of this type. Specifically, a nematic liquid crystal compound, a smectic liquid crystal compound and a cholesteric liquid crystal compound can be applied to the liquid crystal layer 8 as a liquid crystal compound having no polymerizable functional group.
Examples of nematic liquid crystal compounds include biphenyl compounds, terphenyl compounds, phenylcyclohexyl compounds, biphenylcyclohexyl compounds, phenylbicyclohexyl compounds, trifluoro compounds, phenyl benzoate compounds, cyclohexyl benzoate phenyl compounds , Phenylbenzoic acid phenyl compounds, bicyclohexylcarboxylic acid phenyl compounds, azomethine compounds, azo compounds, azooxy compounds, stilbene compounds, tolane compounds, ester compounds, bicyclohexyl compounds, phenylpyrimidine compounds And biphenyl pyrimidine compounds, pyrimidine compounds, and biphenyl ethyne compounds.

Examples of smectic liquid crystal compounds include ferroelectric polymer liquid crystal compounds such as polyacrylates, polymethacrylates, polychloroacrylates, polyoxiranes, polysiloxanes, and polyesters.
As a cholesteric liquid crystal compound, cholesteryl linoleate, cholesteryl oleate, cellulose, a cellulose derivative, polypeptide etc. can be mentioned, for example.

  In the liquid crystal cell 4, a sealing material 19 is disposed to surround the liquid crystal layer 8. The upper laminate 5U and the lower laminate 5D are integrally held by the sealing material 19, and the liquid crystal material is prevented from leaking. For example, a thermosetting resin such as an epoxy resin or an acrylic resin, an ultraviolet curable resin, or the like can be used as the sealing material 19.

  In the light control film 1, an alternating current voltage whose polarity is switched in a predetermined cycle is applied to the transparent electrodes 11 and 16, and an electric field is formed in the liquid crystal layer 8 by the alternating current voltage. Further, the orientation of liquid crystal molecules provided in the liquid crystal layer 8 is controlled by this electric field, and the transmitted light is controlled.

The VA method (Virtical Alignment, vertical alignment type) is applied to the alignment control of the liquid crystal layer 8 in the light control film 1 of the embodiment. In the VA system, an alignment film having an alignment control force in the vertical direction is provided on a transparent electrode formed on a substrate, and the liquid crystal layer 8 is sandwiched between the upper and lower substrates.
In the VA mode, when no electric field is applied, the liquid crystal molecules of the liquid crystal layer 8 are vertically aligned, whereby the light control film 1 blocks incident light and becomes a light blocking state, and the liquid crystal of the liquid crystal layer 8 is applied by applying this electric field. Are horizontally oriented, and the light control film 1 transmits incident light to be in a transmission state.
A light control mode in which light is blocked when no electric field occurs and light is transmitted when an electric field is applied as in the VA mode is referred to as a normally black mode.

However, instead of the VA method, various driving methods such as a TN (Twisted Nematic) method, an IPS (In Plane Switching) method, and a GH (Guest Host) method may be applied.
Here, in the TN method, an alignment film subjected to rubbing processing or the like that has an alignment direction different by 90 ° is attached on a transparent electrode formed on a substrate, and the liquid crystal layer 8 is sandwiched between the upper and lower substrates. The liquid crystal molecules are aligned along the alignment direction of the alignment film by the alignment regulating force of the alignment film, and the other liquid crystal molecules are aligned along the liquid crystal molecules, so that the liquid crystal molecules are aligned in a 90 ° twisting direction. Then, polarizing plates are disposed outside the upper and lower substrates in parallel with the alignment direction of the alignment film.
In the TN mode, when there is no electric field, light passing through the polarizing plate becomes linearly polarized light and enters the liquid crystal. Since the liquid crystal molecules are oriented at 90 ° twist, the incident light is also allowed to pass at 90 °, so that it can pass through the lower polarizing plate. Thereby, the light control film 1 transmits incident light and is in a transmission state.
In addition, although the liquid crystal molecules can stand upright and get twisted by the application of this electric field, the alignment control force of the liquid crystal molecules on the surface of the alignment film is stronger, so that the alignment direction of the liquid crystal molecules remains along the alignment film. In such a state, since the liquid crystal molecules are isotropic to the light passing therethrough, no rotation of the polarization direction of the linearly polarized light incident on the liquid crystal layer 8 occurs. Therefore, linearly polarized light that has passed through the upper polarizer can not pass through the lower polarizer, and the light control film 1 blocks incident light to be in a light shielding state.
A control mode of light which is in the transmission state in the absence of an electric field and in the light shielding state in the application of an electric field as in the TN method is referred to as a normally white mode.

  In the IPS method, electrodes are formed collectively on one substrate, and the amount of transmitted light is controlled by rotating liquid crystal molecules aligned by an electric field by the electrodes in a lateral (horizontal) direction with respect to the substrate. is there.

Furthermore, the GH method is a method using a liquid crystal composition in which a dichroic dye is dissolved as a guest in a host nematic liquid crystal. Since the dichroic dye has a uniaxial light absorption axis and absorbs only light oscillating in the light absorption axis direction, it changes the orientation of the dichroic dye in accordance with the movement of the liquid crystal due to the electric field. By controlling the direction of the light absorption axis, the transmission state of the liquid crystal cell can be changed.
Liquid crystal compositions used in the GH system are roughly classified into positive type and negative type depending on the difference in the long axis direction of liquid crystal molecules when an electric field is applied.
A positive nematic liquid crystal is a liquid crystal whose dielectric constant is large in the long axis direction and small in the direction perpendicular to the long axis and whose dielectric anisotropy is positive. When no electric field is applied, the long axis direction of liquid crystal molecules is relative to the optical axis. It is vertical, and the major axis direction of liquid crystal molecules is parallel to the optical axis when an electric field is applied.
On the other hand, a negative nematic liquid crystal is a liquid crystal in which the dielectric constant is small in the major axis direction and the dielectric anisotropy is large in the direction perpendicular to the major axis, and the major axis direction of liquid crystal molecules is the optical axis when no electric field is applied. They are parallel to each other, and the major axis direction of the liquid crystal molecules is perpendicular to the optical axis when an electric field is applied.

Here, since the dichroic dye molecules are aligned in the same direction as the liquid crystal molecules, when a positive nematic liquid crystal is used as a host, the dichroic dye molecules are shielded when no electric field is applied and are transmitted when an electric field is applied (normally Black mode).
On the other hand, when a negative nematic liquid crystal is used as a host, on the other hand, it is in the transmission state in the absence of an electric field, and in the light shielding state when the electric field is applied (normally white mode).
The dichroic dye used in the GH system is a dye having solubility in liquid crystal and high dichroism, preferably a dye having an order parameter (S value) of 0.7 or more, for example, azo Dichroic dyes such as a system, anthraquinone system, quinophthalone system, perylene system, indigo system, thioindigo system, merocyanine system, styryl system, azomethine system, tetrazine system and the like can be mentioned.
In addition, when the light control film 1 is manufactured by GH system, a linear-polarizing plate can be abbreviate | omitted.
In addition, the liquid crystal cell 4 may drive the liquid crystal material by so-called multi-domain method by patterning of the photo alignment layer or the like, and may further drive by a single domain.
Furthermore, the light control film 1 can be widely applied when using various light control films capable of adjusting the amount of transmitted light, in addition to the above-described light control films using liquid crystals.

[Multi-segment]
FIG. 2 is a view for explaining the detailed configuration of the transparent electrodes 11 and 16 of the light control film 1. FIG. 2 is a plan view of the light control film 1 with the configuration of the light control film 1 other than the transparent electrodes 11 and 16 omitted.
The light control film 1 is manufactured by dividing the transparent electrode 11 and / or the transparent electrode 16 into a plurality of insulated partial electrodes (regions) capable of individually supplying drive power. Thereby, as shown in FIG. 2, the light control film 1 is provided with a plurality of regions (hereinafter, each region is appropriately referred to as a segment) SG1 to SG12 whose transmittance can be changed independently and individually. It is formed by segments.

In addition, although it is also possible to spread a plurality of light control films and make each light control film correspond to the above-mentioned segment, in this case, there may be cases where joints (boundaries) between adjacent light control films are noticeable. Yes, there is a possibility of damaging the appearance.
On the other hand, the light control film 1 of the present embodiment is formed of a single film, and only the transparent electrode constituting the light control film 1 is divided into a plurality of regions (partial electrodes) as described above. It is done. Therefore, while being able to suppress as much as possible the boundary between each segment of the light control film 1 being remarkable, the working efficiency which arrange | positions the light control film 1 can also be improved.

The transparent electrodes 11 and 16 of the light control film 1 are divided, for example, as follows.
The light control film 1 is formed in a substantially rectangular shape in plan view corresponding to the transparent member 29 of the visor described later.
As shown in FIG. 2A, the light control film 1 divides the transparent electrode 16 provided on the rectangular light control film 1 into three in the short direction (vertical direction), and further in the longitudinal direction (horizontal direction). By dividing into four, the transparent electrode 16 is formed on the substrate 15 in a state of being divided into a plurality of partial electrodes 16A to 16L. Further, the transparent electrode 11 facing the transparent electrode 16 is formed on the entire surface of the substrate 6 without being divided. Thereby, the multi-segment light control film 1 having the segments SG1 to SG12 is formed.
In the above description, although the example in which the transparent electrode 16 is divided into 12 is shown, the present invention is not limited to this. The transparent electrode 11 is divided into 12 and the transparent electrode 16 is formed on the entire surface of the substrate 15 You may do so.

Further, as shown in FIG. 2 (b), the transparent electrode 11 and the transparent electrode 16 may be divided similarly to the transparent electrode 16 of FIG. 2 (a). Specifically, transparent electrode 16 is formed of a plurality of partial electrodes 16A to 16L, and transparent electrode 11 is divided so as to correspond to transparent electrode 16, that is, transparent electrode 11 is formed of a plurality of partial electrodes 11A to 11L. As a result, the multi-segment light control film 1 having the segments SG1 to SG12 is formed.
Such division of the transparent electrodes 11 and 16 can be produced by patterning of the transparent electrodes.

The division by patterning of the transparent electrodes 11 and 16 may be a division number other than twelve, and the division numbers of the transparent electrodes 11 and 16 facing each other may be different.
Moreover, in the example shown in the above-mentioned FIG. 2 (a) and FIG.2 (b), the patterning of the transparent electrodes 11 and 16 divides into the rectangular shape (rectangular shape) arranged in the horizontal direction and the perpendicular direction. Although shown, the present invention is not limited to this, and for example, it may be divided by a band shape extending in the vertical, horizontal or diagonal direction, and may be hexagonal shape, trapezoidal shape, parallelogram shape, triangular shape It may be divided by various shapes. In addition, FIG.2 (c) is a figure which shows the example divided | segmented by triangle shape.

In this manner, since the multi-segmenting can drive each of the segments SG1 to SG12 individually, the light control film 1 locally reduces the transmittance to set a specific segment partially in the light blocking state, and can be used as a visor. When applied, it is possible to shield only the necessary part without unnecessarily blocking the view.
Here, as described above, since the light control film 1 of the present embodiment applies a bead spacer to the spacer 12, the transmittance of each segment is more accurately compared to the case where a photo spacer is applied. It can be changed.

  In the present embodiment, as described above, although an example of a light control film having flexibility as a light control member is described, the present invention is not limited to this. For example, the base material of the above-described light control film 1 may be a glass plate to configure a light control member having no flexibility.

〔visor〕
FIG. 3 is a view for explaining a vehicle 20 having the light control system for a mobile according to the embodiment. FIG. 3A is a view of the front side (driver's side) of the rear seat of the vehicle. FIG. 3B is a partial cross-sectional view of the vehicle as viewed from the side.
FIG. 4 is a view showing a cross section parallel to the thickness direction of the visor 22. As shown in FIG.
The visor 22 is a sunshade provided on each of the driver's seat S1 side and the passenger's seat side of the front window 21 of the vehicle (passenger car) 20 as shown in FIG. 3A.

In the visor 22, as shown in FIG. 4, the light control film 1 and the transmission type image display panel 31 are sequentially provided on the entire surface of one surface of the substantially rectangular plate-like transparent member 29 in plan view with an acrylic plate or the like. It is stacked.
One long side of the transparent member 29 of the visor 22 is held by a rod-like holding portion 26 extending along the long side, and one end of the holding portion 26 is a movable member 27 and the front window 21 of the vehicle 20 is Is held movably at the top edge (ceiling) of the As a result, as shown in FIG. 3B, the visor 22 is located relative to the front window 21 in front of the passenger by the retracted position arranged along the ceiling of the vehicle 20 and the movable member 27. It can move between the use position arranged at an arbitrary angle.

More specifically, the visor 22 is configured to be pivotable about a pivot shaft (not shown) provided on the movable member 27 as a pivot center, and the light control film 1 and the transmissive image provided on the transparent member 29 The display panel 31 can be inclined at a predetermined angle.
The visor 22 can detect the inclination θa of the holding portion 26 with respect to the horizontal direction and the inclination θb of the rotation of the transparent member 29 with respect to the vertical line of the floor of the vehicle 20 by the position sensor 27a provided at the root of the holding portion 26 Is configured. The visor 22 is configured to be able to acquire the disposition attitude of the transparent member 29 (the light control film 1 and the transmissive image display panel 31) with respect to the vehicle 20 by the visor position information configured from the information of the inclinations θa and θb. .
As the position sensor 27a, various known detectors such as a displacement sensor and an angle sensor can be applied. Alternatively, the imaging unit 28 described later may be applied as a position sensor, and the inclinations θa and θb of the visor 22 may be detected by image processing of the imaging result inside the vehicle acquired by the imaging unit 28.

Furthermore, the visor 22 includes, in the holding unit 26, an imaging unit 28 for imaging the driver S1 and the passenger seated in the front passenger seat. As a result, the moving object light control system 41 performs image processing on the imaging result acquired by the imaging unit 28 to detect the eye point (eye position) P of each passenger.
The imaging unit 28 may be disposed at a position where the face of the passenger can be imaged, such as a ceiling above the front window 21 or a dash panel, instead of the holding unit 26 of the visor 22.
Here, the visor 22 is disposed such that the transparent member 29 is located closest to the front window 21 in the use position shown in FIG.

The transmissive image display panel 31 is a so-called transmissive display panel that displays image light on the surface (inside) side using external light such as sunlight incident from the back (outside the vehicle) side, and this embodiment Then, a liquid crystal display panel is applied. The transmissive image display panel 31 can transmit incident light when the image is in a non-display state.
As described above, the transmissive image display panel 31 according to the present embodiment displays image light using external light, so that a light source such as a backlight can be omitted, and the configuration of the visor 22 can be simplified. And can be made lighter (thin and smaller).
Specifically, as shown in FIG. 4, the transmissive image display panel 31 is configured by sandwiching the liquid crystal cell 32 by the linear polarizers 33 and 34. Further, in the liquid crystal cell 32, a plurality of transparent electrodes 38 and 39 are formed in pixel units respectively on transparent substrates 36 and 37 made of glass, transparent film material or the like, and the liquid crystal layer 40 is held by the transparent substrates 36 and 37. ing.

The transmissive image display panel 31 is further provided with drive circuit elements for driving the transparent electrodes 38 and 39 of each pixel, a color filter used for displaying a color image, and the like. Here, when the image to be displayed is not a color image but a black and white image, the transmissive image display panel 31 can omit the above-mentioned color filter. In this case, the transmissive image display panel 31 transmits light outside the transmissive image display panel 31. The light transmittance can be improved.
The transmissive image display panel 31 is not limited to the liquid crystal display panel, and in addition, a known transmissive display panel may be applied.

  With the above-described configuration, the visor 22 modulates the amount of external light incident from the outside of the vehicle sequentially through the transparent member 29 and the light control film 1 in the pixel unit of the transmissive image display panel 31 to obtain a desired image Display Thereby, the configuration of the visor 22 can be simplified as compared with the case where a liquid crystal display device using a backlight device mainly used conventionally is provided.

In the visor 22, the transmission axis of the linear polarization plate 34 on the light control film 1 side of the transmission type image display panel 31 and the linear polarization plate 2 on the transmission type image display panel 31 side of the light control film 1 become substantially parallel. In this way, it is arranged (i.e., parallel Nicol arrangement), so that incident light incident from the surface on one side of the visor 22 can be transmitted and emitted from the surface on the other side.
Note that one of the linear polarizer 34 on the light control film 1 side of the transmission type image display panel 31 and the linear polarizer 2 on the transmission type image display panel 31 side of the light control film 1 may be omitted. Good.

In addition, by applying a transparent plate-like substrate such as a glass substrate to one or both of the transparent substrates 36 and 37 of the transmissive image display panel 31, the transmissive image display panel 31 is manufactured in a flat plate shape and transparent The member 29 may be omitted.
Similarly, by applying a transparent plate-like substrate such as a glass substrate to one or both of the substrates 6 and 15 of the light control film 1, a flat light control member having no flexibility is manufactured. The transparent member 29 may be omitted.

FIG. 5 is a diagram for explaining the details of the light control system for a mobile according to the embodiment.
As described above, in the vehicle 20, the visor 22 is disposed at the upper end edge inside the front window 21 of the driver's seat S1 and the front passenger seat.
As described above, in the visor 22, the light control film 1 and the transmissive image display panel 31 are sequentially disposed on the transparent member 29.
The vehicle 20 drives the visor 22 provided with the light control film 1 and the transmission type image display panel 31, the position sensor 27a, the imaging unit 28, the light sensor 42, the incident position calculation unit 47, and the light control film 1 And a light control system 41 for a mobile unit having a display control unit 49 for driving the transmission type image display panel 31.
The light control system 41 for a mobile object uses the light control film 1 provided in the visor 22 to control the light intensity of the sunlight L incident on the driver's seat S1 and the eye point P of the passenger seated in the passenger seat, if necessary. It can be adjusted (blocked). Further, the light control system 41 for mobile body can display a predetermined image for the passenger by the transmissive image display panel 31 provided in the visor 22.

In the present embodiment, the moving object light adjustment system 41 having the incident position calculation unit 47, the drive control unit 48, and the display control unit 49 is provided in an information processing apparatus (for example, the vehicle 20) that executes a control program of the visor 22. And an electronic control unit (ECU 50).
Here, the ECU 50 is an input circuit unit for inputting various sensor outputs provided in the vehicle, various signals such as position information of the vehicle 20, operation signals output from the operation panel, etc., an arithmetic processing unit (hereinafter referred to as "CPU" A control circuit for storing various calculation programs to be executed by the CPU, a control program for the visor 22 described above, a calculation result, etc., control signals for controlling each part such as a drive source (engine) of the vehicle 20, An output circuit unit or the like that outputs a control signal or the like for controlling the film 1 and the transmissive image display panel 31 is provided.
The movable body light control system 41 is not limited to the configuration according to the above control program, and each of the units 47 to 49 constituting the movable body light control system 41 may be configured by dedicated processing circuits. Good.

FIG. 6 is a view for explaining the light sensor 42 provided in the vehicle 20. As shown in FIG.
The light sensor 42 is a sensor that detects the incident direction of sunlight.
As shown in FIG. 6, in the light sensor 42, a light shielding plate 42c having an opening 42b is disposed on the light receiving surface side of a photosensor array 42a in which a plurality of light receiving elements such as photodiodes and phototransistors are two-dimensionally arranged. And be configured. Thereby, the light sensor 42 detects the incident position of the direct light L from the sun S which passes through the opening 42b and is incident from the amount of light received by each light receiving element of the photosensor array 42a, and shifts from the opening 42b. The incident direction of the sunlight L to the vehicle 20 is detected by measuring the amount δ.

Note that various methods can be applied to the detection of the incident direction of the sunlight L, in addition to using the above-described light sensor 42. For example, by applying a GPS (Global Positioning System) receiver mounted in a car navigation or the like, an acceleration sensor provided in the vehicle, and a vehicle speed sensor, position information, posture information, and date and time information of the vehicle 20 are detected. Based on these pieces of information, the direction in which sunlight enters the vehicle 20 may be detected.
Here, the GPS receiver receives signals from GPS satellites, measures the distance between the vehicle and the GPS satellites, and the rate of change of the distance with respect to three or more satellites, thereby determining the current position and the progress of the vehicle. The speed and heading are measured, the acceleration sensor outputs information on the acceleration of the sensor itself (change in speed per second), the vehicle speed sensor converts the detected number of revolutions of the wheel into a pulse signal, It outputs information used to calculate a predetermined vehicle speed, such as the number of pulse signals in time.

The light sensor 42 is disposed at a position where the incident direction can be detected with respect to sunlight incident on the front window 21. In the present embodiment, as shown in FIG. 3, on the dashboard (instrument panel) in front of the driver's seat. Will be placed. The light sensor 42 may be disposed on the visor 22 or may be disposed on the outer edge of the front window 21 of the vehicle 20 or the like.
When the light sensor 42 is disposed on the visor 22, the incident direction of the sunlight L can be detected based on the posture of the visor 22. Further, as described later, when detecting the coordinates of the eye point P by performing image processing on the imaging result by the imaging unit 28 provided in the visor 22, the eye point P is detected with reference to the visor 22 used in various postures. It is also possible to detect the coordinates. Therefore, when the light sensor 42 is disposed on the visor 22 in this manner, the position sensor 27 a of the visor 22 can be omitted.

The incident position calculation unit 47 is a part that calculates the incident position of the sunlight L arriving at the eye point P of the passenger M on the visor 22.
The incident position calculation unit 47 drives the position sensor 27a to acquire information on the inclinations θa and θb of the visor 22, and acquires visor position information based on the position information on the visor 22. Further, the light sensor 42 is driven to detect the incident direction of the sunlight L.
Furthermore, the incident position calculation unit 47 includes an eye point detection unit 47 a, and inputs the image data acquired by the imaging unit 28 of the visor 22 to the eye point detection unit 47 a.
The eye point detection unit 47 a detects the eye point (eye position) P of the passenger M by performing image processing on the image data acquired by the imaging unit 28, and detects the position information of the eye point P. In addition, various methods, such as detecting after detecting a passenger's face, for example, applying the method of template matching to eye point P can be applied widely.
In this process, the eye point detection unit 47 a detects the depth direction of the eye point P (the direction orthogonal to the two-dimensional plane related to the position information obtained by image processing) based on the information of the autofocus in the imaging unit 28. Position information of the eye point P is detected, and the position information of the eye point P is detected by the position information of the depth direction and the two-dimensional position information obtained by image processing. .
The position information in the depth direction may be obtained by obtaining an imaging result obtained by stereo imaging (stereoscopic view) by the imaging unit 28 and detecting the image result by the image processing. It may be detected based on the information of the inclination of the backrest of the seat.

Further, the eye point detection unit 47a identifies the passenger based on the weight of the passenger based on the detection result of the pressure sensor provided on the seat by accepting registration of the passenger's eye point by user operation. The position information of the registered eye point may be detected.
Furthermore, the eye point detection unit 47a detects the weight of the passenger based on the detection result of the pressure sensor provided on the seat when practically sufficient, and the detection result indicates, for example, an eye point based on a standard figure The position information of P may be detected by estimation.

  The incident position calculation unit 47 determines the current position of the sunlight L arriving at the eye point P based on the incident direction of the sunlight L to the vehicle 20, the position information of the eye point P, and the visor position information of the inclinations θa and θb. The incident position on the visor 22 is calculated. More specifically, it is calculated which segment SG1 to SG12 of the visor 22 at the current position the sunlight L enters. As described above, the incident position calculation unit 47 can calculate the incident position of the sunlight L arriving at the eye point P of the passenger M on the visor 22.

The drive control unit 48 includes a power supply unit that outputs driving power to each of the segments SG1 to SG12 of the light control film 1, and is configured by an arithmetic processing unit that controls the power supply unit. The drive control unit 48 locally changes the transmittance of the light control film 1 based on the incident position calculated by the incident position calculation unit 47, and blocks the sunlight L incident on the eye point P of the passenger M. .
Here, in the present embodiment, the local shading of sunlight L is described as an example in which the corresponding segment is changed to the shading state in which the transmittance is set to the minimum value, but the present invention is not limited thereto. . For example, the transmittance of the segment relating to the light shielding may be changed to a predetermined transmittance according to an arbitrary setting of the passenger, an incident light amount of the sunlight L detected by arranging a separate sensor, or the like. In this way, for example, when the sunlight is blocked by clouds as in cloudy weather, the sunlight L is not blocked more than necessary, and the light entering the car is blocked more than necessary You can prevent that.
In addition, the other segments which are not set in the light blocking state are set so as to maximize the transmittance so as to be in the light transmitting state so as not to block extraneous light.

Specifically, in the example shown in FIG. 5, the segments SG7 and SG11 are set to the light shielding state, and the sunlight L entering the eye point (eye) of the driver M through the segments SG7 and SG11 is shielded. It is possible to avoid a decrease in the visibility of the driver M due to the sunlight L.
In addition, with respect to the segments SG1 to SG6, SG8 to SG10, and SG12 other than the segments SG7 and SG11, external light can be sufficiently incident to the inside of the vehicle as a light transmitting state, and the view in front of the vehicle 20 can be secured. .

From the above, the light control system 41 for a mobile object is provided with the light control only for the sunlight coming to the eyes of the passenger provided to the visor 22 by tilting the visor 22 forward and moving it from the retracted position to the use position. The light can be locally blocked by the film 1.
As a result, the mobile body light control system 41 can ensure that the sunlight does not enter the eyes of the passenger without blocking the view of the passenger as much as possible. In addition, when the entire surface of the light control film 1 is blocked by an abnormality, the forward view of the passenger can be secured by moving the visor 22 to the retracted position, and sufficient safety can be achieved. It can be secured.

FIG. 7 is a diagram for explaining the driving state of the light control film and the transmissive image display panel provided in the visor. FIG. 7 is a view of the visor 22 as viewed from the inside of the vehicle.
The display control unit 49 drives the transmissive image display panel 31 provided in the visor 22 to display desired image information for the passenger. Here, on the transmissive image display panel 31, the image information of the car navigation device, the image information of the back monitor, the information of the vehicle 20 (traveling speed, engine speed, information of the direction indicator, etc.) are displayed as image information. Image information to be displayed may be appropriately switched by the operation of the passenger.

  The display control unit 49 of the present embodiment changes the display position of the image information so as to avoid a portion overlapping the segment of the light control film 1 corresponding to the incident position of the sunlight L obtained by the incident position calculation unit 47. Thereby, the mobile body light control system 41 can reliably display the image information desired by the passenger to the passenger without unnecessarily blocking the view of the passenger.

Specifically, as shown in FIG. 5 and FIG. 7, when the segments of the light control film 1 to be in the light blocking state based on the calculation result of the incident position calculation unit 47 are SG7 and SG11, the display control unit 49 A region overlapping the rectangular region (indicated by hatching in FIG. 5) by the segments SG1, SG2, SG5 and SG6 is selected so as to avoid the region overlapping the segments SG7 and SG11, and an image is formed in this region Display information
Further, in a region overlapping with the other segments (SG3, SG4, SG8 to SG10, SG12), the transmission state is maintained without displaying an image.
Note that the display control unit 49 displays a black image in a region overlapping with the segments SG7 and SG11 set in the light shielding state by the light control film 1, and blocks the sunlight L incident on the eye point P more reliably. If light shielding by the light control film 1 is sufficient, the corresponding region may be in a light transmitting state.

  Thereby, as shown to Fig.7 (a), the light modulation system 41 for mobile bodies makes the segments SG7 and SG11 of the light control film 1 light-shielding state, and the sunlight L which injects into a passenger's eye point P is made. In addition to light shielding, image information can be displayed in a region overlapping the rectangular region formed by the segments SG1, SG2, SG5, and SG6 of the transmissive image display panel 31 using external light. Further, in the area corresponding to the other segments (SG3, SG4, SG8 to SG10, SG12) of the visor 22, it is possible to make the front visible without interrupting the driver M's line of sight.

Further, from the state shown in FIG. 7A, for example, the segment where the light L enters the light shielding state by changing the traveling direction of the vehicle 20 and the incident position of the sunlight L arriving at the eye point P is the segment SG7, When changing from SG11 to segments SG6 and SG10, the mobile body light adjustment system 41 sets the segments SG7 and SG11 of the light adjustment film 1 in the light transmission state as shown in FIG. , SG10 in the light blocking state. Thereby, even if the incident direction of the sunlight L changes, the mobile light adjustment system 41 can prevent the sunlight L from being incident on the eye point P of the driver.
In addition, the moving body light control system 41 changes the area for displaying an image corresponding to this from a rectangular area overlapping with the segments SG1, SG2, SG5, and SG6 to a rectangular area overlapping with the SG3, SG4, SG7, and SG8. In addition, a region overlapping with the segments SG1, SG2, SG5, SG9, SG11, and SG12 is set to the light transmission state.

  Thereby, even when the incident position of the sunlight L changes, the incident of the sunlight to the eye point P is surely prevented, and the image information is displayed to the passenger without unnecessarily blocking the visibility of the passenger. be able to.

  In addition, when sunlight does not enter from the front window 21 in the case where the sun is behind the vehicle 20, or in the case of cloudy weather, rainy weather, night, etc., shading control of the sunlight L by the light control film 1 is unnecessary. Therefore, for example, the mobile body light control system 41 displays image information on the entire surface of the visor 22 or on the central portion of the visor 22 (for example, the regions corresponding to the segments SG2, SG3, SG6, and SG7). May be

The mobile body light control system 41 operates when power is supplied from an alternator and a battery mounted on the vehicle 20.
Here, the alternator is a generator connected to the axle of the vehicle 20 or the engine, and a rectifier called rectifier that rectifies the generated AC voltage and converts it to a DC output voltage, and an integrated circuit And a voltage control device or the like called a voltage regulator which controls the output voltage.
The voltage regulator monitors the output voltage and controls the field current of the alternator because the voltage output from the alternator changes in accordance with the number of revolutions of the axle of the vehicle 20 or the number of revolutions of the engine. The output voltage is adjusted. The voltage regulator supplies power at a voltage at which the electrical components of the vehicle 20 operate normally even under ever-changing operating conditions.

The battery is, for example, a secondary battery such as a lead battery, a nickel hydrogen battery, or a lithium ion battery, and stores the output voltage from the alternator and discharges the stored output voltage to supply power to the light control system 41 for mobile use. Supply.
In addition, although the power supply method to the light control system 41 for moving bodies showed the example to which electric power is supplied from the alternator and battery mounted in the vehicle 20, it is not limited to this, For example, a vehicle Power is supplied from any one of the alternator and the battery mounted on 20, and a battery for the light control system 41 for a mobile unit is separately provided so that power is supplied from the battery, and others The well-known power supply method of may be applied.

The drive control unit 48 of the dimmer system 41 for a mobile body may drive the dimmer film 1 with an alternating voltage or may drive it with a direct current voltage. In this case, a converter may be provided in the power supply unit to the light control film 1, and the power supplied from the battery or the alternator may be converted according to the type of voltage used by the light control film 1.
In the light control film 1 of the present embodiment, the fluctuation of the transmittance is usually controlled by the application of an alternating voltage. However, light emitted from an external light emitter such as a traffic light may be difficult to see due to the frequency of the AC voltage. In such a case, the drive control unit 48 of this embodiment is used. Can switch the voltage supplied from the converter from the AC voltage to the DC voltage, and can minimize the difficulty in viewing the light emitted from the light emitter.

FIG. 8 is a flowchart showing the processing procedure of the light control system for a mobile according to the embodiment.
Due to the configuration of each of the units 27a and 42 to 49 described above, the movable body light control system 41 repeatedly executes the processing procedure (SP1 to SP6) illustrated in FIG.

The dimmer system 41 for a mobile provided in the vehicle 20 acquires visor position information based on the inclinations θa and θb of the visor 22 by the position sensor 27a of the visor 22 and inputs the acquired information to the incident position calculation unit 47 (SP1).
Further, the moving object light control system 41 detects the incident direction of the sunlight L by the light sensor 42 and inputs it to the incident position calculation unit 47 (SP2). Further, the image data taken by the imaging unit 28 of the visor 22 is input to the eye point detection unit 47a, and the position information of the eye point P of the passenger M is detected (SP3).
Then, the mobile body light control system 41 calculates the incident position of the sunlight L arriving at the eye point P of the passenger on the light control film 1 based on the information (SP4), and the light control is performed based on the calculation result. The drive control of the light film 1 is performed to control the transmitted light of each segment, and the sunlight L arriving at the eye point P is blocked (SP5).
Further, the moving object light control system 41 displays the image information on the transmission type image display panel 31 so as to avoid the area overlapping the segment set in the light blocking state (SP6).
